The liquid coagulant in the coagulant box can be transported to the connecting pipe through the operation of the delivery pump, and the liquid coagulant can enter the hollow rotating shaft through the connecting pipe. Finally, the liquid coagulant is discharged from the end of the hollow rotating shaft into the sewage. At the same time, the operation of the third driving device can make the hollow rotating shaft rotate, and the coagulant and sewage can be stirred by the stirring rod. During the coagulant addition process, the utility model can be pushed to move along the sewage treatment pool in cooperation with the moving wheels.

[0008] Preferably, the lower end of the coagulant box is equipped with moving wheels, and there are four moving wheels in total, and the four moving wheels are arranged in an array with respect to the coagulant box.
